Answer:
The concentration is simply 36%
Step-by-step explanation:
In this question, we are concerned with calculating the concentration of a new mixture formed from mixing some liters of each of two vinegar variants of different concentrations.
We proceed as follows;
The concentration of the new solution will contain 12% of 13L vinegar A and 70% of 9L vinegar B
13L of vinegar A will contain 13 * 12% = 13 * 0.12 = 1.56
9L of 70% vinegar B will contain 9 * 70% = 9 * 0.7 = 6.3
Now, the new mixture has a total volume of 13 + 9 = 22L
The concentration of the new mixture will thus be;
(1.56 + 6.3)/22
= 0.357 and that’s approximately 0.36 or simply 36%
Answer/Step-by-step explanation:
A series is events coming one after another but a sequence is in a certain order.
arithmetic is the difference between two constant terms while geometric is the ratio between two constant terms.
arithmetic: -
geometric: ÷
Answer:
First angle is 45 and the second angle is 60
Step-by-step explanation:
150 + 105 = 255
360 - 255 = 105
the ratio is 3:4 I add the ratio so 7
105 / 7 = 15
The first angle with the ratio of 3 is 15 x 3 = 45
The second angle with the ratio of 4 is 4 x 15 = 60
